ABSTRACT:
A yarn brake has a tubular brake housing with an upper and a lower end. A lower brake ring is connected to the lower end of the brake housing. A brake ring carrier is positioned in the housing at a distance above the lower brake ring and has a central axis about which it is rotatable. The brake ring carrier is axially slidable within the brake housing. A spring is positioned in the brake housing between the upper end and the brake ring carrier for biasing the brake ring carrier in a downward direction. An upper brake ring is connected to the brake ring carrier so as to face the lower brake ring. A brake cartridge rests between the upper and the lower brake rings. An abutment is connected to the brake housing and extends radially into the brake housing. The brake ring carrier has a plurality of support shoulders distributed over the periphery of the brake ring whereby these support shoulders are axially spaced relative to one another. Depending on a rotational position of the brake ring carrier one of the support shoulder is supported on the abutment. The abutment is arrestable at various axial positions in the brake housing.
